Find the degree of the polynomial: a^3+3a^2−5a

emmainna [20.7K]

Answer:

The degree of the polynomial is 3

Step-by-step explanation:

Given:

$a^3+3a^2-5a$

To Find:

The degree of the polynomial= ?

Solution:

The degree of the polynomial is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial

Here in the given polynomial

$a^3+3a^2- 5a$

The terms are

$a^3$

$3a^2$

$5a$

The term $a^3$ has the largest exponent of 3

Note: The degree of the polynomial does not depend on coefficients of the terms

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 4 feet per second.

Ad libitum [116K]

Let $d_m,\ d_e$ represent the depth of the miner and equipments elevator, respectively. We know that equipment elevator descends with a velocity of $v_e = 4$ feet per second, and the miners one descends with a velocity of $v_m = 15$ feet per second.

If we start counting time ( $t=0$ ) when the equipment elevator begins to descend, after $t$ seconds its depth will be

$d_e(t) = v_et = 4t$

On the other hand, the miner elevator follows the same rule, but we have to use its velocity, and remember that it starts with a delay of thirty seconds:

$d_m(t) = v_m(t-30) = 15(t - 30)$

Now, we have to wait the 30 seconds of delay, and then another 14 seconds. This means that we want to know the positions of both elevators when $t = 44$ . Let's plug this value into the two equations:
